What are Cephalopods?

Octopuses, squid, cuttlefishes and nautiluses are marine molluscs, related to snails and slugs. They're found in all the world's oceans and at all depths. They can be colorful or transparent and range in size from less than an inch to more than 50 feet. More than 800 species of cephalopods have been identified. These animals share a similar body plan that includes a head and eyes, a mantle and siphon, arms and tentacles, a beak and a file-like radula.

Octopusonly have arms(eight of them)

Nautilusonly have tentacles(up to 100 of them!)

Squidhave eight arms + two retractable tentacles

Adaptations

Quick-Change Artists

Octopuses, squid and cuttlefishes create an amazing array of colors, patterns, textures and shapes for camouflage and communication. Chromatophores—color organs made of nerves and muscles and tiny sacs of pigment—transform these animals as they hide from predators or hunt for prey.

Clever Hunters

Squid and cuttlefishes use mesmerizing color changes to lure or confuse prey, then they snatch a snack using two long tentacles. Octopuses catch their prey by surprise, using camouflage, jet propulsion and the sure grip that comes with having eight arms.

Movers and Shakers

Some cephalopods lumber along the seafloor, crawling or walking. Others use jet propulsion, filling their muscular bodies with water, then squirting it from tubular siphons. Some animals use a combination of these methods to move through the water.
